Variables | |
msg_hclass_t | sip_warning_class [] |
Header class for Warning header. | |
tag_typedef_t | siptag_warning |
Tag for Warning header object. | |
tag_typedef_t | siptag_warning_str |
Tag for string with Warning header value. | |
#define SIP_WARNING_INIT | ( | ) |
Initializer for structure sip_warning_t.
A static sip_warning_t structure for Warning header must be initialized with the SIP_WARNING_INIT() macro. For instance,
#define SIPTAG_WARNING | ( | x | ) |
Tag list item for pointer to a Warning header structure sip_warning_t.
The SIPTAG_WARNING() macro is used to include a tag item with a pointer to a sip_warning_t structure in a tag list.
x | pointer to a sip_warning_t structure, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_WARNING_REF().
#define SIPTAG_WARNING_STR | ( | s | ) |
Tag list item for string with Warning header value.
The SIPTAG_WARNING_STR() macro is used to include a tag item with a string containing value of a sip_warning_t header in a tag list.
s | pointer to a string containing Warning header value, or NULL. |
The string in SIPTAG_WARNING_STR() can be converted to a sip_warning_t header structure by giving the string s has second argument to function sip_warning_make().
The corresponding tag taking reference parameter is SIPTAG_WARNING_STR_REF().
|
inline |
Test if header object is instance of sip_warning_t.
Check if the header class is an instance of Warning header object and return true (nonzero), otherwise return false (zero).
header | pointer to the header structure to be tested |
1 | (true) if the header is an instance of header warning |
0 | (false) otherwise |
|
inline |
Copy a list of Warning header header structures sip_warning_t.
The function sip_warning_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next
) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.
home | memory home used to allocate new structure |
hdr | pointer to the header structure to be copied |
When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.
|
inline |
Duplicate a list of Warning header header structures sip_warning_t.
Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure |
hdr | header structure to be duplicated |
When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.
|
inline |
Make a Warning header from formatting result.
Make a new sip_warning_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_warning_t.
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
|
inline |
Initialize a structure sip_warning_t.
An sip_warning_t structure for Warning header can be initialized with the sip_warning_init() function/macro. For instance,
|
inline |
Make a Warning header structure sip_warning_t.
The function sip_warning_make() makes a new sip_warning_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. |
s | string to be decoded as value of the new header structure |
|
extern |
Header class for Warning header.
The header class sip_warning_class defines how a SIP Warning header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_warning_t header structure.
